Heat a skillet with the oil on medium heat. When good and hot add the potatoes flat side down. Let them brown for 3 or 4 minutes and do not move them. Turn them over and add the stock, lemon juice, garlic and spices.
Put a cover on the skillet and cook for 10 - 15 minutes. Finish by adding in the butter and spooning the liquid over the potatoes.
Serve and enjoy!
